High-quality active and passive components engineered for outstanding performance, durability, and standard compliance.
In modern telecommunications, the 4 Core Single Mode Fiber Optic Cable has established itself as the backbone of high-speed local loop distribution and long-haul connections. By utilizing a single-mode glass core designed for the transmission of a single ray of light (mode) over long distances, this cable reduces optical attenuation and modal dispersion to absolute minimums.
The "4 Core" configuration is particularly popular because it balances high-density data channels with localized space management. It allows for multi-directional transmission paths (typically utilizing two cores for transmission/receipt and reserving the other two for backup redundancy or network scaling). It operates predominantly at the 1310nm and 1550nm wavelengths, adhering strictly to the ITU-T G.652.D and G.657.A1/A2 standards for bend-insensitivity.
Engineered for extreme performance and resistance, our cables are manufactured to withstand harsh environmental conditions.
Manufactured using high-purity silica glass to ensure minimum attenuation (<0.35 dB/km at 1310nm and <0.22 dB/km at 1550nm), meeting the highest global requirements.
Available in LSZH (Low Smoke Zero Halogen), PVC, and PE (Polyethylene) jackets to cater to indoor safety standards and outdoor direct-buried applications.
Designed with central strength members (CSM) consisting of FRP (Fiber Reinforced Plastic) or high-tensile steel wire to prevent mechanical pulling damage.

Years of sales and service experience have enabled us to win customers from different regions. Today, we have customers from East Asia, Southeast Asia, Middle East, Eastern Europe, Western Europe, Northern Europe, South America, North America, North Africa, and South Africa.
Win-win cooperation is our constant goal. Many our OEM and ODM products won the Telecom Operator tender and satisfy end-user request.
Our main terminal telecom operators include:
Meeting stringent global standards to ensure seamless customs clearance, site safety compliance, and robust legal deployment.
All our 4 Core Single Mode Fiber Optic Cables distributed to Europe comply with the Construction Products Regulation (CPR) Class B2ca, Cca, and Dca standards, ensuring high performance in fire safety.
Environmental preservation is crucial. We certify that all components, including sheathing materials, are completely free of hazardous substances such as lead, cadmium, and polybrominated biphenyls.
We provide full customs support documentation including Certificate of Origin (Form E, Form F), CE certificates, and localized technical datasheets translated into German, Spanish, French, and Portuguese.
How Kocent Optec leverages industrial clusters in China to deliver unbeatable value, quality, and delivery speed.
Based in the heart of the global electronics supply chain, we procure high-purity glass preforms and aramid yarn directly from major localized raw material producers, lowering basic production costs.
Our facility features high-speed drawing towers, automated cable color coding lines, and automated secondary coating lines, allowing us to process bulk orders of over 10,000 km per month.
With shipping hubs located near major marine transport routes in Shenzhen, Guangzhou, and Hong Kong, we easily secure quick vessel bookings and reduced shipping lead times.
We align our manufacturing processes with the requirements of corporate procurement offices, infrastructure tenders, and telecom operators.
From customizable cable surface markings (meters, part numbers, logos) to customized wooden reel dimensions, we construct the product according to your exact corporate specification sheet.
Whether you require a custom prototype length of 1 km for a local pilot test or 100 km for an extensive network construction roll-out, we accommodate your needs with scalable minimum order quantities.
We work directly alongside contractors bidding on national broadband tenders by providing technical layout documentation, structural drawing specifications, and priority production queues.
Optimized deployment of 4 Core Single Mode Fiber Optic Cable across diverse global topologies.
Perfect for FTTH drop connections from the local distribution box directly into corporate or residential properties. The 4-core structure ensures a dedicated line for internet access, VoIP services, and future expansions.
Designed for deploying extensive CCTV security arrays, road sensors, and automated traffic light systems. A 4-core cable transmits high-bandwidth feed streams with minimal delay over long distances.
Designed to link distributed PLCs, sensor nodes, and telemetry stations inside steel factories, chemical plants, and solar farms. Shielded armored sheaths protect against high electromagnetic interference.
How next-generation infrastructure shifts are reshaping the utilization of single-mode systems.
Tight spaces inside smart buildings demand G.657.A2 fibers that can survive acute angles without macro-bending losses, replacing the rigid older G.652.D variants in localized areas.
Modern telecommunication companies require carbon-neutral components. Our R&D is focused on producing high-performance, bio-based recyclable LSZH sheathing compounds.
To reduce onsite splicing time, the industry is moving toward pre-terminated plug-and-play 4-core cables equipped with factory-tested IP-rated connectors.
